[新闻] 轰动软件业界,QuickTransit闪亮登场

      使用任意的处理器，在任意操作系统上，运行任意应用程序，而性能没有任何损失。你肯定会说这是一场梦吧。Linux程序运行在Windows上，Mac程序运行在Linux上，Intel代码库运行在PowerPc芯片上......一个不可能完成的任务。

　　在硅谷崛起的Transative公司告诉你：旗下的QuickTransit软件已允许程序直接运行在多种硬件平台上，诸如Mac，PC，大型机，服务器。并且这个过程不需用户干涉和没有任何性能损失。

　　该公司宣称：QuickTransit软件解决了程序在一个平台转换到另一平台的接口。在一种特定平台编写的应用程序几乎能在其他平台上运行，且不需对内部程序作任何修改。

　　公司总裁和CEO Bob Wiederhold放出豪言：由于以前的软件都是依靠特定的处理器运行的，QuickTransit软件将会开创一个全新世界。通过它，你能够使用更多的软件。而其中的一个关键突破是性能。你根本分辨不出解析软件和原始软件的区别。

　　分析家Jim Turley表示：太激动人心了。行动将证明它的不显著地方特显其出众之处——简简单单的运行。他已经在膝上型电脑的Windows系统上成功运行Linux的Gimp图像编辑软件。系统在一系列的增强图形转换处理下，都能流畅地运行，并表演出优异的性能。可以肯定对你说性能没有任何损失。本来认为运行会拖满情况却没有发生，更加没有一点延迟。事实上，它运行得好正常，反应相当快。

不要和我谈理想，不要和我谈设计，不要和我谈艺术，不要理我，我只是个潜水员，还长得象狗……趟了这混水就只能往前划呀呀……

[em093]其实我是一个设计师，对这个软件最感兴趣的是可以在PC上用Mac系统，这样就可以用到支持alpha通道的图形界面，不用忍受windows可恶的锯齿了…… -------------------- looks like dog

First, an integration “FUSE” allows QuickTransit to be easily integrated into the target system. Second, a dynamic binary translator tackles the challenge of moving from one instruction set architecture to another. Third, an operating system mapper translates operating system calls from the source system to the target system in situations where the source and target operating systems are different. Finally, a graphics subsystem mapper translates graphics system calls from the source to the target system in situations where the source and target graphics systems are different.

Operating system call mapping from any Unix/Linux-like operating system or any mainframe operating system to any Unix/Linux-like operating system is supported.

Windows 算不算是Unix/Linux-like os?

這句話是不是說只能用在Unix/Linux-like的操作系統上?Unix Linux肯定是可以的, Mac好像也算是Unix-like的,Windows呢? -------------------- [a=http://go2west.512j.com/]西へ·独自旅行人のBLOG[/a]

QuickTransit allows software that has been compiled for one processor/operating system to be run on another processor/operating system without any source code or binary changes.
只能用于軟件的跨平台啊
不能用于操作系統,比如說Windows建在PowerPc上之類的

History of Transitive

The origin of Transitive’s QuickTransit technology dates back to 1992, when an unrelated computer design project underwent a late change of instruction-set-architecture. After a short gestation period, the development of QuickTransit began in 1995 at The University of Manchester, England, which has a long and distinguished history of innovation in computing technology.

The initial research goals of the project were to determine the effectiveness of a modular, re-targetable, dynamic binary translator, providing 100% compatibility between pairs of different processor instruction sets. These goals, coupled with the then-absent pressure of producing a commercial product, allowed exploration of the best way to design intermediate representations of the software being translated, which paid dividends in the modularity and optimizing capability of the resulting translators.

The University research team quickly discovered that the novel principles underlying QuickTransit would lead to a unique combination of configurable translators, providing high fidelity and outstanding performance. Patents were filed on key components of the technology, and several options for commercializing the technology were explored during1998 and 1999.

QuickTransit’s technology shows promise in many areas. Besides easing the application migration of software between different conventional computer families, it has potential in the design of application-centered CPUs, in dynamic re-optimization of performance-critical software at run-time, and as a component in computer systems deeply embedded in consumer electronics – from cell phones and PDA's through digital entertainment centers and games consoles. One key challenge during the technology’s early days was to establish a commercial focus on a suitable subset of these fields.

Transitive was founded in 2000 as the vehicle to develop QuickTransit technology for the commercial market. Initial technical work was focused on developing the University technology into a robust, commercial and industrial software base, and to complete the many features necessary for full customer deployment.

Development contracts were signed in 2001 and 2002 with early customers acting as technology partners, and 2003 saw the beginning of focused sales activity with key customer prospects in the industry. While the details of customer contracts are confidential, Transitive expects public availability of multiple QuickTransit products in 2004.

仔细看了一下，似乎主要是硬件方面的虚拟，操作系统只支持“Unix-like”的。硬件转化机制属于实时翻译，可能类似于Virtual PC for Mac，当然应该更加优化和模块化。
